8 Claims.

This invention relates to a paper roll support, and is more particularly directed to an adjustable support to accommodate for various widths'of paper rolls.

The-device is shown, attached to an adding machine carriage that is provided with a platen around which the free end of the paper is fed from a roll supported by the device, the platen of the machine being of suflicient length to accommodate for different widths of paper.

The chief objects of the present invention are the provision of an adjustable paper roll support which is simple in construction, durable andinexpensive to manufacture and simple in operation, and which may be attached to or made an integral part of the machine.

Another object is the provision of a paper roll support which may be adjusted to difierent positions to accommodate for various widths of paper rolls, and which support, when adjusted, may be spread to permit of the insertion of the roll.

A further object is to provide a paper roll support which is adjustable to accommodate for various widths of rolls and which has yieldable means coacting therewith for permitting of its positioning to readily insert the roll and for temporarily supporting the same in a position to permit unhampered access to the support.

And a still further object is the provision of a paper roll support that is adjustable and arranged to be swung in a position to permit of accessibility thereto for inserting the roll and to be retained in its swung position during the insertion and in its operative position when the roll is inserted.

The invention is illustrated as attached to an adding machine carriage designated as a Whole as It, comprising a bottom-portion-II and side walls I2 and I3, and with a platen I4 pivotally supported on the sidewalls.

The purpose of the invention is to provide a support for a paper rollA which has its free end fed around the platen and on which impressions are to be made, and which support may be adiustable to accommodate for various widths of rolls.

The support comprises a pair of L-shaped standards I5 and I6 which are secured at II-I8 to the bottom portion II of the carriage I0, and these standards are provided with aligned openings I9 and 26, respectively, into which a shaft 2i is journaled. A pair of arms 22 and 23 are carried in spaced relation on the shaft 2I and these arms are each provided at their free ends with roll-engaging heads 24 and 25. The arm 22 is secured to the shaft, while the arm 23 is keyed for turning movements with the shaft and for independent longitudinal movements thereon. This arm 23 has a relatively long hub 26 secured thereto which is provided with a flattened portion 21 in the bore 28 thereof which engages a flattened portion 29 milled longitudinally of the shaft 2|. The hub 26 is provided with a shoulder 30 adjacent the arm 23, and its free end extends through an opening 3| in the side wall I2. A compression spring 32 surrounds the hub 26 and is interposed between the shoulder 30 thereof and the side wall I2 and serves to urge the arm 23 against the standard I5.

The shaft 2| is arranged for longitudinal sliding movements in the openings I9 and 20 of the standards, and is provided with a plurality of engageable annular recesses 33, 33a and 331), any one of which may be brought into alignment with a retaining member 34 secured at 35 to the standard I 6. This retaining member 34 is preferably provided with relatively flat top and bottom edges 36 and 31, respectively, the top edge extending slightly above the lower portion of the opening 20 while the bottom" edge of the retaining member engages the inturned end of the standard I6 to prevent its displacement. Between the engageable recesses 33, and 331), the shaft 2| is also provided with a flattened portion 38, which, when aligned with the top edge 36 of the retaining member 34 permits the shaft 2I to be slidably moved longitudinally in the standards I5 and I6.

When the shaft 2I is moved longitudinally, the flattened portion 29 thereof will slide in the hub 26 of the arm 23 which is being yieldingly held against movement by the spring 32. The arm 23 is provided adjacent the shaft 2| with a Vertical edge 39 and an inclined edge 40, which are adapted to be brought into engagement with a spring 4! secured at 42 to the bottom portion ll of the carriage.

While in their normal positions, the arms 22 and 23 are swung downwardly and rest on the bottom portion II of the carriage, and while in this position,'the vertical edge 39 of the arm 23 is engaged by the spring 4! which serves to yieldingly retain the arms in their lowered positions.

At this time, the arm 23 may be moved outwardlyagainst the tension of the spring 32 to permit of the insertion of the roll A between the rollengaging heads 24 and 25 of the arms, and during this movement of the arm 23, the vertical edge 39 thereof will be slidably carried on the spring 4|. After the roll A is in position, the arm 23 is then released and the spring 32 will urge the same toward the roll with its engaging head 25 in position to support the roll.

When a larger or smaller paper roll A is to be attached to the machine, the arms 22 and 23 are positioned the proper distance apart depending upon the width of the roll. This is accomplishe in the following manner:

The arm 22 is swung upwardly and its movement carries the arm 23 therewith through the shaft 21 and the inclined edge 40 of the arm 23 is then brought into engagement with the spring 4| which retains the arms in their raised positions. When the arms are in this raised position, the flattened portion 38 of the shaft 2| is then aligned with the top edge .36 of the retaining member 34 and the shaft may then be moved longitudinally in the standards [5 and IS with the arm 22. This longitudinal movement of the shaft 21 is for the purpose of varying the space between the arms 22 and 23 to accommodate for different widths of rolls A, and when properly positioned with one of the engageable recesses 33, 33a or 332) aligned with the retaining member 34, the arms may then be rocked downwardly which causes the flattened portion 38 of the shaft to be rocked out of alignment with the top edge 36 of the retaining member 34 and with this member then aligned in the recess selected. The paper roll A may then be positioned in the manner as above described by manually forcing the arm 23 outwardly against the tension of its spring 32 and then releasing the same permitting the roll-engaging heads 24 and 25 of the arms 22 and 23 to pivotally retain the roll.

I contemplate as being included in these improvements all such changes, variations and departures from what is thus specifically illustrated and described as fall within the scope of the appended claims.
